MORTIMER B. BURGESS, OF LINCOLN UNIVERSITY, PENNSYLVANIA.

FOLDING UMBRELLA.

SPEGIFIGATION forming part of Letters Patent No. 744,476, dated November17, 1903.

Application filed April 1, 1903- To all whom it may concern.-

Be it known that I, MORTIMER B. BURGESS, a citizen of the United States,residing at Lincoln University, in the county of Chester and State ofPennsylvania, have invented new and useful Improvements in FoldingUmbrellas, of which the following is a specification.

My invention relates tonew and useful improvements in folding umbrellas;and its object is to provide a frame of novel construction by means ofwhich the umbrella can be folded into compact form.

A further object is to provide means whereby the ribs of the frame maybe simultaneously folded upon each other.

A further object is to employ an extensible handle having novel meansfor locking the same in either extended or shortened position.

With the above and other objects in view the inventionconsists'inarranging upon the tubular handle of the umbrella a series ofribs each of which is preferably formed of three sections hingedtogether. A stretcher is pivoted at opposite ends to a runner upon thehandle and to the outer section of its rib at a point between the endsthereof. A link is pivoted at opposite ends to this stretcher and to theadjoining ends of the other two sections of the rib. By arranging theribsections, stretcher, and link in this manner when the runner is drawndown upon the novel construction and combination of parts handle therib-sections will be folded upon each other in such a manner as toreduce the length of the rib approximately one-half.

The invention also consists in the further Serial No. 150,632. (Nomodel.)

erence, 1 is a tubular rod having oppositelyarranged apertures 2 and 3near one end, and rib-sections L are pivotedto the rod 1 near the otherend thereof. An intermediate ribsection 5 is pivoted at opposite ends toeach section 4 and to an outer. ribsection 6, and a stretcher 7 ispivoted at its ends to a runner '8upon'rod 1 and the section 6 at apoint between its ends. Alink is pivoted at oppositeiends to theadjoining. ends of sections 4 and 5 and the stretcher 7, respectively,and the combined lengths of link 9 and rib-section 4. are preferablyequal to the distance from the pivot 10 of link 9 to pivot 11 of thestretcher and from said pivot to the point of connection betweensections 5 and 6. A spring-pressed dog 12 is mounted upon runner 8 andis adapted when the umbrella is extended to project into an aperture 13,formed within rod 1.

When it is desired to fold the umbrella, dog 12 is depressed, so as torelease the runner, and said runner is moved longitudinally upon rod 1.This will cause stretcher 7 to draw inward upon the outer rib-section 6,and at the same time link 9 will draw downward upon the adjoining endsof the sections 4. and 5. This will cause rib-sections to fold into thepositions shown in Fig. 2. The runner can be locked in lowered positionby placing the dog in the aperture 2, before referred to. rod 14 isslidably mounted in the tubular rod 1 and has aslot 15 near its innerend, within which is pivoted alever 16, having oppositelyextendingprojections 17. When the rod 14. is pressed inward and the umbrella isfolded,

dog 12 will project into a recess 18 formed within said rod and lock therod within the tubular portion 1. To extend rod 14:, dog 12 is depressedand the rod drawn outward. As soon as the extensions 17 of lever 16arrive opposite the apertures 2 and 3 they will be moved automaticallythereinto by means ofthe preferred form of my invention; but I do notlimit myself thereto, as I am aware that modifications may be madetherein.

Having thus described the invention, what is claimed as new is- 1. In afolding umbrella, the combination with a rod having a runner thereon; ofa stretcher pivoted to the runner, an outer ribsection pivoted at apoint between its ends to the stretcher, an inner rib-section pivoted tothe rod, an intermediate rib-section pivoted to the outer andinnersections, and a link be tween the stretcher and the adjoining ends ofthe inner and intermediate sections.

2. In a folding umbrella, the combination with an extensible rod, and arunner mounted upon the rod; of an inner rib-section pivoted to the rod,a stretcher pivoted to the runner, an outer rib-section pivoted at apoint between its ends to the stretcher, an intermediate rib-sectionpivoted to the outer and inner rib-sections, and a link between theadjoining ends of the inner and intermediate rib-sections and thestretcher.

3. In a folding umbrella, the combination with an extensible rod, andmeans forlocking said rod in extended or shortened position; of a runnermounted upon the rod, means for locking the runner to the rod, an innerribsection pivoted to the rod, a stretcher pivoted to the runner, a linkpivoted to the stretcher at a point between its ends and to the outerend of the inner rib-section, an outer rib-section pivoted at a pointbetween its ends to the stretcher, and an intermediate rib sectionpivoted to and connecting the outer and inner rib-sections.

4. In a folding umbrella, the combination with a tubular rod, andfolding ribs pivoted thereto; of a runner slidably mounted upon said rodand connected to and adapted to fold the ribs, means for locking therunner to the rod, a slotted rod slidably mounted within the tubularrod, and a spring-pressed catch pivoted within said slotted rod andadapted to engage the tubular rod.

In testimony whereof I affix my signature in presence of two witnesses.

MORTIMER B. BURGESS.
